Systems and Methods for Detecting and Mitigating Spoofed Satellite Navigation Signals

4. The method of claim 1, the first location is based, at least in part, on one or more non-GNSS positioning sources.

6. The method of claim 5, wherein the first location and the second location are located on a boundary of the spoofing region.

9. The method of claim 5, further comprising transmitting the first location and the second location to a server, wherein determining the spoofing region comprises receiving data indicating the spoofing region from the server.

11. The method of claim 1, wherein determining the at least one GNSS signal corresponding to the GNSS satellite has experienced the first transition comprises determining a discrepancy associated with the first set of GNSS signals based on a detected change in signal characteristics of the at least one GNSS signal corresponding to the GNSS satellite.

12. The method of claim 11, wherein the signal characteristics comprise frequency, phase, or signal strength, or a combination thereof.

13. The method of claim 1, wherein determining the at least one GNSS signal corresponding to the GNSS satellite has experienced the first transition comprises determining a discrepancy associated with the first set of GNSS signals based on a detected change in data obtained from the at least one GNSS signal corresponding to the GNSS satellite.

14. The method of claim 13, wherein the data comprises location, velocity, heading, time, date, almanac data, or ephemeris data, or a combination thereof.

16. The device of claim 15, wherein, to determine the first location, and in response to the first transition comprising the transition from the not spoofed state to the spoofed state, the one or more processors are configured to determine the first location based on the first set of GNSS signals prior to the first transition.

17. The device of claim 15, wherein, to determine the first location, and in response to the first transition comprising the transition from the spoofed state to the not spoofed state, the one or more processors are configured to determine the first location based on one or more locations determined after the first transition.

18. The device of claim 15, the one or more processors are configured to determine the first location based, at least in part, on one or more non-GNSS positioning sources.

20. The device of claim 19, wherein the one or more processors are configured to determine the spoofing region such that the first location and the second location are located on a boundary of the spoofing region.

23. The device of claim 19, further comprising a transceiver, wherein the one or more processors are further configured to transmit the first location and the second location to a server via the transceiver, and wherein, to determine the spoofing region, the one or more processors are configured to receive data indicating the spoofing region from the server via the transceiver.

25. The device of claim 15, wherein to determine the at least one GNSS signal corresponding to the GNSS satellite has experienced the first transition, the one or more processors are configured to determine a discrepancy associated with the first set of GNSS signals based on a detected change in signal characteristics of the at least one GNSS signal corresponding to the GNSS satellite.

26. The device of claim 25, wherein the signal characteristics comprise frequency, phase, or signal strength, or a combination thereof.

27. The device of claim 15, wherein to determine the at least one GNSS signal corresponding to the GNSS satellite has experienced the first transition, the one or more processors are configured to determine a discrepancy associated with the first set of GNSS signals based on a detected change in data obtained from the at least one GNSS signal corresponding to the GNSS satellite.

28. The device of claim 27, wherein the data comprises location, velocity, heading, time, date, almanac data, or ephemeris data, or a combination thereof.
